Chemical Nomenclature Unit Valence Value
The valence value of an element is defined as the number of electrons an atom of that element will gain/lose/share when forming a compound. Elements have a valence value determined by their group on the Periodic table unless otherwise indicated by the name.

Cross-Over Rule for Writing Formulas
STEPS sodium chloride
magnesium oxide
calcium fluoride
lithium sulphate
aluminum carbonate
1. Write down the symbols of the elements in the order given in the name.
Na Cl
Mg O
Ca F
Li SO4
Al CO3
2. Write the valences above the elements symbol.
1 1 Na Cl
2 2 Mg O
2 1 Ca F
1 2 Li SO4
3 2 Al CO3
3. Divide the valences by the highest common multiple.
1 1 Na Cl
1 1 Mg O
2 1 Ca F
1 2 Li SO4
3 2 Al CO3
4. Cross-over valences Na1Cl1 Mg1O1 Ca1F2 Li2(SO4)1 Al2(CO3)3 5. Drop all 1’s and unnecessary brackets
NaCl MgO CaF2 Li2SO4 Al2(CO3)3
Notes:
a) You should be able to do all 5 steps in your head when you are finished the unit. b) When naming compounds, the least electronegative element is usually written first. c) Groups of elements such as SO4
2- and CO3
2- are referred to as radicals or polyatomic ions. These radicals
behave as if they were a single entity and follow the cross over rule in the same manner as other single elements. Brackets are used in the formula only if there are 2 or more of the radical indicated in the formula. For example, brackets are used in Al2(SO4)3 but not Na2SO4.
Binary Ionic Compounds
A binary compound contains 2 elements only.
Rules for Binary Ionic Compounds: a) The name of the binary compound always ends in "ide". b) The first mentioned element may have more than one valence and if it does this must be indicated in
the name. c) If the valence of the first element is not indicated in the name, their valence value is determined by
their group on the Periodic table.
A) Binary Compounds where the first element has 1 valence only
Use rule “c” and the cross-over rule. Silver has a valence of 1, zinc and cadmium have a valence of 2.
Examples:
sodium oxide Na2O calcium sulfide CaS magnesium bromide MgBr2

K2S ____potassium sulfide_________
Al2O3 ____aluminum oxide__________
B) Binary Compounds with Multivalent Elements
Many transition metals and some other elements have multiple valence values and therefore can form multiple compounds with the same non-metal. Due to this it is necessary to indicate the valence of the metal in the name of the compound using either the Stock (IUPAC or Roman Numeral) or Classical (“ous” and “ic”) method. The second element (non-metal) always has a valence equal to the value as determined from its group in the periodic table. The table of multivalent elements that you have been given must be MEMORIZED!
Method 1: Stock/IUPAC/Roman Numeral Method
This is the currently preferred method as the valence of the first is indicated using the corresponding Roman Numeral in brackets following the name of the first element. Examples:
iron(III) chloride FeCl3 tin(IV) iodide SnI4 phosphorus (III) oxide As2O3 mercury(II) oxide HgO Exercise: For all exercises give the name if the formula is provided and the formula if the name is provided.

Method 2: Classical/"ous' and "ic" Method
This method can be used when the multivalent element has 2 possible valences. The name of the element ending with "ous" denotes the lower valence value and the name of the element ending with an "ic" denotes the higher valence values. In some cases, the Latin name for the element is used.
iron: ferrous (valence = 2) and ferric (valence = 3) gold: aurous (valence = 1) and auric (valence = 3) copper: cuprous (valence = 1) and cupric (valence = 2) tin: stannous (valence = 2) and stannic (valence = 4) lead: plumbous (valence = 2) and plumbic (valence = 4) cobalt cobaltous (valence = 2) and cobaltic (valence = 3) nickel nickelous (valence = 2) and nickelic (valence = 3) mercury mercurous (valence = 1) and mercuric (valence = 2) platinum platinous (valence = 2) and platinic (valence = 4)
*Some elements having more than two valence values or oxidation states use specific values for the "ous" and the "ic".
nitrogen ous = 1 ic = 2 chromium ous = 2 ic = 3 manganese ous = 2 ic = 3 phosphorus ous = 3 ic = 5 arsenic ous = 3 ic = 5 bismuth ous = 3 ic = 5
Examples: stannous chloride SnCl2 phosphorous oxide P2O3 arsenic phosphide As3P5 nitric oxide NO

Common Radicals or Polyatomic Ions
Radicals or polyatomic ions are groups of atoms that are treated as a single entity when writing formulas and names. The following list of common radicals (polyatomic ions) must be memorized along with their valences. Positive polyatomic ions replace metals in an ionic compound and a negatively charged polyatomic ion goes in place of the non-metal. If more than 1 of the radical is required in the chemical formula, brackets are placed around the radical’s formula with the subscript outside the bracket.

Acids
There are three groups of acids: 1. binary acids 2. oxy acids 3. derived oxy acids
1. Binary Acids This is a very small but common group of acids. The following rules apply to all of the members.
1. All have the prefix “hydro” and end with “ic”. 2. All must contain hydrogen as the first element. 3. Use the normal cross-over-rule to determine the formula. 4. All are made by dissolving the gas in water and must be so indicated by using (aq) behind the formula. 5. Have no oxygen in their formula
Examples: hydrochloric acid HCl(aq) hydrosulfuric acid H2S(aq) hydrocyanic acid HCN(aq)
Exercise: For all exercises give the name if the formula is provided and the formula if the name is provided.
hydrobromic acid __HBr(aq)__
hydroiodic acid __ HI(aq)___
hydrotelluric acid ___H2Te(aq)_
hydroselenic acid ___ H2Se(aq)_
hydrofluoric acid ___ HF(aq)__
hydrosulfuric acid ___ H2S(aq)__
2. Oxy Acids
This is a larger group of acids. They are alike in that they all contain H, O and at least one other non-metal element. All members of this group of acids follow the rules below.
1. The name of the acid ends in “ic”. 2. The name of the associated radical ends in “ate”. 3. The valence value of the associated radical is equal to the number of acidic hydrogens in the acid. 4. Since these acids are made by reacting a non-metal oxide with water, (aq) is not required but may be used.
The following 6 oxy acids and their associated radicals along with their valences must be memorized.
Name of the Acid Formula of the Acid
(aq)
Name of the
associated radical
Formula of the
associated radical
(aq)
valence value for the
associated radical
acetic acid HC2H3O2 acetate C2H3O2- 1
nitric acid HNO3 nitrate NO3- 1
fluoric acid HFO3 fluorate FO3- 1
carbonic acid H2CO3 carbonate CO32- 2
sulfuric acid H2SO4 sulfate SO42- 2
phosphoric acid H3PO4 phosphate PO43- 3
NOTE:
Using the periodic table it is possible to write the names and formulas for a number of other oxy acids using the fact that members of the same chemical family have similar chemical properties. Elements of the same chemical family (group) follow the pattern of the memorized oxy acid immediately above the element of interest.
Example: memorized acid: fluoric acid = HFO3 therefore: chloric acid = HClO3 iodic acid = HIO3 bromic acid = HBrO3
If hydrogen is joined with the radicals learned earlier a few more acids can be formed.
chromate = CrO42- chromic acid = H2CrO4 cyanate = CNO- cyanic acid = HCNO

3. Derived Oxy Acids
Theses acids are all derived from the parent oxy acids which you are to memorize. The table below shows the rule to determine the derived oxy acids from the parent acid. When adding or removing oxygen atoms from the parent acid, the number of hydrogens on the acid and the valence of the associated radical remain the same as the parent.
Type of Acid Associated Radical Example
Parent Oxy Acid + 1 O per______ic per______ate perchloric acid HClO4 perchlorate ion ClO4-

Salts
The word, salt, is the general term given to a class of compounds which can be formed when an acid and a base neutralize each other. According to this definition then, most of the compounds dealt with in the section on binary compounds could be considered to be salts formed from a base and a binary acid. In the same manner, salts are formed from a base and an oxy acid or derived oxy acid.
Examples: sodium sulphate Na2SO4 calcium phosphate Ca3(PO4)2
aluminum carbonate Al2(CO3)3 zinc perchlorate Zn(ClO4)2 cupric nitrite Cu(NO2)2 stannous hypoiodite Sn(IO)2

Acid Radicals and Acid Salts
1. Acid Radicals In certain circumstances the oxy acids with multiple acidic hydrogens are able to lose the hydrogens one at a time. This results in radicals with acidic hydrogens still attached which are referred to as acid radicals.
Step 1: H3PO4 (aq) H+ (aq)+ H2PO4-(aq) Step 2: H2PO4
-(aq)
H+ (aq)+ HPO4
2-(aq) Step 3: HPO4
2- (aq) H+(aq) + PO4
3-(aq)
Radical Name Valence PO4
3-(aq) Phosphate 3
HPO42-
(aq) monohydrogenphosphate 2 H2PO4
-(aq) dihydrogenphosphate 1
Notes:
a) valence = # of hydrogen removed from the acid OR valence of non-acid radical-# of H’s still attached b) mono may be left off a monohydrogen acid radical c) for oxy acids with 2 acidic hydrogens (diprotic acids), the prefix “bi” may be used in place of monohydrogen
(eg. HCO3- can be named as bicarbonate or monohydrogen carbonate)
